In my Xt, several times the BitDefender icon in the system tray has become colored gray.
There's a message when I hover my mouse: "BitDefender has stopped responding, restart the system, if the problem persists contact support." That implies that this is a known problem. Does anybody have any info?
When I try to hit Ctrl-Alt-Delete - nothing happens.
I try to restart & then to log off, but usually it doesn't work. I have to power off the PC by pressing the power on/off button & afterwards powering the PC on again. when it comes back up, everything is OK until the next time.
I don't know when or why this happens.
